It seems like Sigma has the right idea with the DPM series. Wide, normal or tele to choose from.

Although I like a lot about the RX1 and X100, I find myself thinking that I would be more inclined to buy one if the standard lens were 50mm and I could buy a wide angle converter to get 35mm or possibly 28mm when needed.

Q. Would Fuji produce a tele-conversion lens for the X100/X100s?A. We tried to make a teleconverter for the X100 but we found that the image quality has degraded. But we were able to achieve no image degradation with the wide-angle conversion lens, hence we offer it.

The physical size of a FF fast 50mm could be an issue on the RX1 (maybe f/1.8 wouldn't be too much of a stretch?), but after handling a used X100 today both with and without the converter lens attached, I left thinking that a larger lens would not be a bad thing. Is there any chance a 50mm equivalent version could be in the works?

The RX-1 is 35mm because more people prefer that focal length on a fixed lens camera. Far more flexible than a 50mm. If you want a 50m perspective, there are lots of choices with APS and m4/3 cameras. Why not buy one of those?

Apart from a review video about a video camera, what other evidence do you have that Sony will make a FF still-photography NEX camera? That camera was announced with the a99 and RX-1. Perhaps Sony thinks the FF still camera line is well covered.

Thanks for all the replies everyone. I guess the thing that was bugging me was limiting a high-end enthusiast product to a single fixed lens and no other options.

After more thought, I realized that Sony, Sigma and Fuji actually had plans, but different execution.

DP1m, DP2m and DP3m provide a full range of useful focal lengths, but you need to buy a new body with each.

The X-100 28mm extension lens provides a wider option without needing to buy a second body, but apparently their engineers were not able to develop a tele-adapter lens that met IQ requirements. So, their customers need to go to a different product line for portraits and other telephoto applications.

The Sony has only its sensor cropping setting to get a telephoto effect. With 24mp on a FF sensor, this is a legitimate option.

So, I guess they thought this through more than I intitially assumed.

To bad the tele-adaptor for the X-100 failed, Fuji would have been nearly unbeatable with 28mm, 35mm, and presumably something in the 50-90mm range for the second add-on.
